the role of pulmonary rehabilitation and airways clearance techniques in the multidisciplinary management of non cf bronchiectasis

Conditions: Non-cystic Fibrosis Bronchiectasis

Summary: pulmonary rehabilitation programs are part of the multidisciplinary treatment of some chronic respiratory diseases such as copd (chronic obstructive pulmonary disease). although clinical guidelines of other diseases such as non-cystic fibrosis bronchiectasis (ncfbe) discuss the benefits of these programs in quality of life and exercise tolerance, evidence of such intervention in ncfbe patients is insufficient. longer studies are needed with larger sample sizes and optimized to maximize the response and maintain long-term benefits. the present study aims to examine the effects in exercise tolerance of a pulmonary rehabilitation program combined with respiratory physiotherapy in patients with ncfbe. it is a randomized controlled clinical trial with a total duration of 24 months. the intervention will be performed during 12 weeks and then will be a period of 12 months of maintenance. this is a multicenter study involving the following hospitals: hospital clinic, hospital la plató and hospital del mar of barcelona, hospital josep trueta of girona, royal infirmary of edinburgh and fondazione maugeri di lumezzane of italy. subjects will be randomized into three groups in a ratio (1: 1: 1) (1) pulmonary rehabilitation (2) chest physiotherapy and (3) pulmonary rehabilitation + chest physiotherapy. hospital la plató from barcelona will be responsible for carrying out the control group. the primary endpoint will be the test of "endurance shuttle walk test".
